General Comments:

First identification of 32Ar nuclide: 1977Ha29: isotope produced by V(p,X) E=600 MeV, followed by mass separation at ISOLDE-CERN facility.

1985Bj01: 32Ar produced by 40Ca(p,3p6n) reaction at E=600 MeV, followed by mass separation at ISOLDE-CERN facility.

The study of decay of 32Ar is currently in progress (2006BoZZ). Other decay studies: 2008Bh08, 2002Fy01, 1999Ad10, 1999Th09, 1993Ad02, 1993Sc16

Mass determinations: 2009Sc09, 2006Tr03, 2003Bl17

Mass deduced by IMME analysis: 2010Ka30

Nuclear radii, hyperfine structure: 2002Oz03, 2000Ge20, 1996Kl04

9Be(32Ar,31ArX) E=65.1 MeV/nucleon: 2004Ga33: deduced occupancy of deeply-bound neutron state

C(32Ar,x) E≈950 MeV/nucleon: 2002Oz03. Measured interaction cross section, deduced proton skin features.

Q-value: Note: Current evaluation has used the following Q record

Q-value: Estimated uncertainty: Δ(S(n))=210 (2011AuZZ)

Q-value: Q(εp)=9553.7 20, S(2n)=39830 500 (syst), S(2p)=2716 3 (2011AuZZ)

Q-value: Values in 2003Au03: S(n)=21560 210 (syst), Q(εp)=9555.5 23, S(2n)=38430 300 (syst). S(p), Q(α), S(2p) are the same as in 2011AuZZ
